viiELL-DRILUNG. CABLE.

T will whom, 1' t DML!! cone/:rn:

Be it known that I, J osEriI REID, a citizen of the United States,'and aresident of Oil City, in the county of Venango, State of' Pennsylvania,have invented certain new and useful Improvements in Well-Drilling(lables,

of which the following is a specification.

It is generally well knpwn that for successfully drilling ldeep wellsthe elasticity oi" the drilling-ropel plays an important part in thestroke of the tool. ropes, however,

.llemp which have the quality of e asticity, are undesirable for deepwell-drilling for well-known reasons. It has been attempted to combinethe hemp rope with a steel cable by splicing the steel cable to the hemprope-that is 'to say, by weaving the strands of'th'e steel cable overand under the strands of the hemp rope. This method is objectionable,because the joint is notdurable, it being found that the i hemp ro e andrelay the strands of the hemp rope tig itly and closely about the steelrope as a core or center, suitably secure the ends o the strands of thehem rope, and clamp the splice or joint thus pro 4uced at suitableintervals by semicylindrical clamps held together by rivets passingthrough both the hemp and steel ropes without cutting orv breaking thefiber or strands in either. The end of the steel rope is preferably.tapered before being introduced into the hem rope by removing a suitablenumber of t e individual wires from its several strands, and the taperedend is wire Wound or bound to prevent unraveling. The end ispreferablyprovided with a further Winding or binding below each rivet to preventuiilaying or unraveling of the strands of the wire rope under the pullof the A through-rivet.

My invention Will be fully understood upon reference to the accompanyingdrawings, in which- Figure 1 is a view of the joint produced by myinvention. Fig. 2 isa view of the two Specification of Letters Patent.'Application filed March 7, i905. Serial No. 248,812.

ropes presented. coaxially. Fig. 3 is a tripsig.

4 is a longitudinal section through the end of the joint and itsfinishing-clamp.

A represents the joint to be forined,which consists of the central steelor wire ro e core l, thesurrouiiding hemp rope 2 lai about the core, theclamps 3, 4, and 5 for securing the hemp rope to the steel core andpreventing'relative longitudinal movement between the parts.v

In producing my improved well-drilling cable I take a suitable length ofhemp rope, preferably haWser-laid, and unravel theends, as shown at 2ain Fig. 2. I then take a length of steel or Wire cable which, with thelength of Manila rope, will be suiicient for. the drilling operations tobe undertaken, and I ta er the `end of the steel rope, as shown at 1a, ycutting back one or more of the wires on each strand, after which thetapered end is bound, as shown at 6, by means of a wire or by brazing orsoldering. I also bind it, as shown at 7, at a point adjacent to thelocation of each rivet to be referred to.

In producing the improved splice the tapered eno 1a of the Wire rope isdrawn into the end of the rope 2 by the wires 10, the strands 2l aretwisted at the proper pitch to correspond to the angle of lay to beimparted to the strands, and said strands are laid about the steel-ropecenter. When a sufficient length of lay has been made, the joint isfinished by applying the clamps 3, 4, and 5, which are secured by rivetspassing through both the Wire and manila ropes immediately above thewindings 7 thereon, While clamp 5, being eX- teriorly threaded, receivesa ta ered sleeve 23, which has been passed over t e end ofthe wire ropeprevious to the commencement of the operation of forming the splice. Bymeans of this clamp 5 and threaded taper sleeve 23 the ends of the laidstrands may be permanently secured and the desired taper inish beprovided at the end of the splice.

A s lice or joint produced as herein describe will be as strong as theweaker ofthe two ropes. It will work satisfactorily over pulleys orguide-slieaves without producing undue wear on the parts, and there willbe no cutting or undue wear upon the strands of the rope at the-spliceor elsewhere.

v The term's laid or laying are used in this specification in theirtechnical sense as understood by ropemakers--that is to say, to conveythe idea of laying the'strands of a IIO rope b twisting and spirallywinding' them. Thus t e term laid joint conveys the idea of a jointformed byusing one of the rope ends as la core and taking the unlaidstrands of the other rogo and twisting and Winding them about sai coreor windin them while maintaining the twist that the have alreadyreceived in the manufacture o1Y the rope.' y

Having thus described my invention, the following is what I claim as newtherein 'and desire to secure by Letters Patent:

1; A composite Well-drilling cable, having` its sections united by alaid`oint.

2. A composite Well-drillmg cable having.

' rope around the wire rope andsecuringV them n' by clamps.

5. A composite ro e having the end of its steel rope wound or ound, andthe strands of its hemp rope laid about said steel rope by twisting andWinding, and secured thereon by a c amping-rivet passing diametricallythrough both ropes just above the binding on the steel rope.

6. A composite rope havin the end of its wire section tapered and bounat the tapered end and above the same, and having the end of its hemsection unlaid, and thestrands thereof tig tly twisted and closely woundu on the steel section and secured thereto by c amps and diametricthrough-rivets.
